Comments
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Magnesian iron skarn (Newberry and others, 1997; Cox and Singer, 1986; model 18d)
Comment (Geology): Age = Cretaceous; this deposit is in the east contact zone of the Kugruk pluton, which has yielded a K/Ar age of 94.9 +/- 2.9 Ma (Till and others, 1986, p. A-15).
Comment (Geology): Age = Chron age is for metavolcanic rocks that host the mineralization.
Comment (Reference): Primary Reference = Newberry and others, 1997
Comment (Workings): Workings / Exploration = The general area is extensively mantled with tundra; the prospect was initially explored by core drilling. Some core may still be stored at Independence (BN076).
Comment (Geology): Geologic Description = This magnetite-rich skarn prospect was discovered and core drilled by Placid Oil and Minerals in the mid-1970's. Although tundra cover is extensive in this area, the deposit is well expressed in aeromagnetic data. A large, positive, north-south trending aeromagnetic anomaly over this prospect is about 0.4 mile wide and 2 miles long. The deposit contains massive to brecciated magnetite in dolomite with blebs to stringers of pyrite and chalcopyrite (Hudson and others, 1977). Newberry and others (1997) classify this prospect as a magnesian iron skarn developed in dolomite. It contains clinohumite, olivine, diopside, and idocrase. Serpentine minerals replace diopside and olivine and phlogopite is present. A sample of the skarn contained 0.06 ounces/ton Ag, 0.0003 ounces/ton Au, 0.2 % Cu, 0.02 % Zn, 0.01 % Co, and 45 % Fe (Newberry and others, 1997, Table 2). This deposit is in the east contact zone of the Kugruk pluton, which has yielded a K/Ar age of 94.9 +/- 2.9 Ma (Till and others, 1986, p. A-15).
